The Quick Read: The program that fits depends on where your equity sits and whether the lender on the new purchase accepts borrowed down-payment money. A DSCR home equity line on a rental you already own can supply the cash, and it is reviewed on that rental’s income, not yours. The short-term rental itself then needs its own separate purchase loan.
- The line is a standalone second lien behind your existing first mortgage, or a standalone first lien on a rental with no mortgage, qualified on rent, subject to underwriting.
- Typical ceilings through select programs: 70% combined loan-to-value on a second lien, and up to 75% loan-to-value on a first lien at the top credit tier.
- The line is never closed together with a purchase, so open it on a seasoned rental before you go under contract.
- The purchase lender decides whether borrowed money counts as the down payment, and reserves are a separate test.
- Plan for two payments. The line’s payment is not in the new property’s coverage ratio, but it comes out of your real cash flow.
Two Loans, Not One Product
Nobody sells one loan that does both jobs. Using a DSCR HELOC for a short-term rental down payment means two separate loans with two separate approvals.
Loan one is the home equity line on a rental you already own. It supplies the cash. Loan two is a DSCR purchase loan on the short-term rental. It buys the property and is judged on that property’s income against its own payment.
Some pages use DSCR HELOC loosely, as if one product covered both. That loose usage hides the question that matters, which is how the two loans fit together. The sections below answer it in order.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. For the full background on how these loans work, Lendmire’s complete DSCR loans guide covers it end to end.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment the lender uses to test the property.
DSCR HELOC: a revolving line of credit secured by a non-owner-occupied rental and qualified on that rental’s rent instead of the owner’s personal income.
Standalone second lien: a line that sits behind the first mortgage you keep, without touching that mortgage.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line, followed by a repayment period when you pay it down.
Borrowed funds: down-payment money that came from a loan instead of your savings.
Seasoning: the waiting period a lender wants after you buy or refinance a property before you borrow against it.
Reserves: liquid cash a lender wants left over after closing, counted separately from the down payment.
How Underwriting Treats the Line, Step by Step
The line is underwritten to the rental securing it, in this order.
1. Eligibility of the property. It must be a non-owner-occupied one-to-four-unit rental. Your own home and second homes are outside this program.
2. The rent test. The lender divides gross monthly rent by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, which makes it a stress payment. Programs we see in the network set the minimum at 1.10x, subject to underwriting.
3. Which rent counts. Rent is the lesser of the appraiser’s Form 1007 market rent (the appraisal form that estimates long-term rent) or the lease. A lease above market counts only with three months of receipts. A lease must be in place, and a two-to-four-unit building may have at most one vacant unit.
4. The second-lien wrinkle. Whether the first-mortgage payment joins the qualifying payment on a second lien is the lender’s own calculation. Do not assume either way until the file is run.
5. Credit. Typically a 720 score on a second lien and 700 on a first lien, using the lender’s own credit report. Expect no 30-day mortgage late in the last 12 months and a 48-month wait after a bankruptcy, foreclosure, short sale or deed-in-lieu.
6. Valuation. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Larger lines require a full interior appraisal. Appraisal waivers are not accepted.
7. Seasoning. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
The file is reviewed on the rental’s income: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. It is not undocumented. The lease, credit report and valuation are all in the file. There are no reserves and no cash to close on the line itself.
Second Lien, First Lien, and the Other Ways to Raise a Down Payment
The line comes in two shapes, and the shape depends on whether the source rental carries a mortgage.
Second lien. You keep the first mortgage and add the line behind it. Combined loan-to-value runs up to 70% at a 720 score or better, on lines from $50,000 to $500,000. Below 720 there is no second-lien option.
First lien. The rental has no mortgage, so the line goes in first position. Loan-to-value (LTV) runs up to 75% at 740 or better, and 70% from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling. A declining-market flag can lower any ceiling by 5 points. These are ceilings, not offers. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Line mechanics. At least 80% of the line is drawn at closing, and never less than $50,000. Later draws must be at least $5,000. You get a 5-year interest-only draw period on the drawn balance, then a 25-year repayment period, with a 30-year maturity. The rate is variable.
The 80% draw rule matters for sequencing. You pay interest on most of the line from day one, so size the line to the down payment instead of opening a bigger one just in case.
Here is how the options compare. Other programs are described under their own rules, not this program’s.
| Option | Reviewed on | Keeps your first mortgage? | Main watch-out |
|---|---|---|---|
| DSCR HELOC on a rental | Rent (1.10x test) | Yes, as a second lien | 6-month seasoning on the source rental |
| Investment-property HELOC on personal income | Your income and debts | Usually yes | Your own debt ratios drive approval |
| Bank statement HELOC | Documented deposits | Varies by program | Income documentation still required |
| DSCR cash-out refinance | Rent | No, it replaces it | You give up the existing first mortgage |
| Cash or partner capital | Not applicable | Not applicable | Ties up savings or adds a partner |
A line on your own primary residence is a different, owner-occupied bank product. This program is never offered on an owner-occupied home.
Will the Purchase Lender Accept Borrowed Money?
This is the question that decides everything. A line of credit is general-purpose money, and the lender on the short-term rental purchase decides whether it counts.
Across the wholesale network Lendmire works with, treatment runs along a spectrum. Some programs accept documented line proceeds as the down payment and ask only for a clean paper trail: the line agreement, the draw statement, and the transfer into your account and then into escrow. Others want the funds to sit for a period first. Others limit how much of the down payment can be borrowed. Large retail lenders are often the least flexible.
Three buckets are tested separately: the down payment, the closing costs and the reserves. Borrowed money may pass the first and fail the third. Many purchase lenders exclude borrowed funds from reserve counts. The line can cover the down payment without covering the cushion.
Ask the purchase lender in writing before you draw. Draw, then ask, is the order that creates surprises.
The CFPB describes a home equity line as open-end credit that usually carries a variable rate, so payments can change month to month. It also says payments are often significantly higher once repayment begins. Its HELOC booklet makes the same point. The risk is real when you use a line to buy a hold-for-years property.
A fully borrowed down payment adds a second risk. You would then have no cash of your own in the deal. The new mortgage and the line together approach financing the whole purchase. That can work when the property’s cash flow covers both payments. It leaves little margin when it does not.
How the Short-Term Rental Income Gets Counted
How the lender counts short-term income varies by program, and the choices shape the ratio.
Evidence usually comes from one of three places: a projection from a short-term rental data provider for a property with no history, documented platform income, or an appraisal that includes a short-term income analysis. Some programs also want hosting experience, which can be a problem for a first-time buyer of a short-term rental.
The appraisal form matters. Class Valuation, an appraisal-management company, argues that Form 1007 is a long-term rent form and cannot support short-term income. It says applying the form to a short-term rental can produce an artificially low coverage ratio. If the lender defaults to the long-term figure, a strong Airbnb-style property can show thin coverage on paper.
Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. A permit or HOA restriction can break the income projection that the whole plan rests on.
Do not confuse this with the line itself. The Form 1007 rent test applies to the source rental that secures the line, which needs a lease. It does not apply to the short-term rental you are buying.
Where the General Rule Breaks
The simple version is that a seasoned rental funds the next purchase. These cases are where it does not hold.
- The source rental was just bought or refinanced. The seasoning rule above applies, so a fresh purchase cannot fund the next one right away.
- The source property is a short-term rental with no lease. The line requires a lease in place, so a property that only hosts guests may not fit.
- Excluded property types. Rural-designated property, condotels, row homes, leaseholds, land trusts, age-restricted communities, mixed-use and commercial or agricultural property are outside this program. So is a property listed for sale in the prior 2 months or one with a solar lien.
- Borrower eligibility. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers are not eligible.
- Exposure limits. The program allows at most 5 loans or $2,500,000 per borrower, which matters if you are building a portfolio.
- Insurance. Hazard insurance must cover both liens, with flood coverage where required.
- Vesting in an LLC. Vesting the source rental in your LLC is allowed on an investment property, subject to program terms. The purchase lender has its own entity rules.
- Footprint. This program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
A Worked Example in Percentages and Ratios
Run the numbers on a paid-off rental in the top credit tier, with a 740 score. As a first lien, the line could reach up to 75% LTV of the property’s value, subject to the valuation. If the rental carried a first mortgage instead, the combined ceiling would be 70% CLTV at 720 or better. With a mortgage balance at 40% of value, the new line could use the remaining 30% of value at most. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Say rent on that rental covers the stress payment at roughly 1.2x. That clears the 1.10x minimum on a modeled basis, subject to the lender’s own calculation.
Now the purchase side. You buy a short-term rental and the purchase lender runs coverage on that property alone. The ratio is the same whether the down payment came from savings or from the line, because the line’s payment is not in the property’s coverage ratio.
Your real cash flow tells a different story. You now owe the new mortgage and the line’s payment. In the draw period the line is interest-only on the drawn balance. When repayment starts, the payment steps up. Stress-test a weak-season month, not an average one. If the property cannot carry both payments in a slow month, the structure is too thin, however good the ratio looks.
What Makes the Best DSCR HELOC Program Depend on Your Situation?
Your situation sets the answer, because the lenders that write this program differ on leverage, valuation and borrowed-funds treatment. A broker that shops multiple wholesale lenders matches the scenario to the program. Lendmire is that broker. It does not lend, and every file is underwritten individually.
Use this table as a starting point.
| Your situation | Structure that usually fits | Why |
|---|---|---|
| Seasoned rental with a mortgage and strong rent | Second-lien line | Keeps your first mortgage intact |
| Paid-off rental, 740 score or better | First-lien line | Highest leverage tier |
| Large equity need above $500,000 | First-lien line with the 65% ceiling | Larger lines carry a lower ceiling |
| Equity sits only in your own home | Consumer-income line or cash-out elsewhere | This program is not offered on owner-occupied homes |
| Source rental bought or refinanced recently | Wait or use another source | The seasoning rule applies |
| Purchase lender rejects borrowed funds | Cash, partner capital or a cash-out refinance | The purchase lender decides |
What to prepare: the source rental’s lease and rent history, your first-mortgage statement, the entity documents if an LLC holds title, and written confirmation from the purchase lender on borrowed funds.
When Not to Use This
Skip the strategy when the new property barely covers its own mortgage, because adding the line’s payment pushes cash flow negative. Skip it when the purchase lender rejects borrowed funds or caps the share you can borrow. Skip it when the source rental is the only cash cushion you have.
Plan the exit before you draw. The line should be repaid by a paydown, a refinance or a cash-out before the draw period ends. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
A true zero-down purchase is not what this is. The line shifts where the down payment comes from. It does not remove the down payment.
Frequently Asked Questions
Can a DSCR HELOC cover the entire down payment on a short-term rental?
Sometimes, but the purchase lender decides. The line is reviewed on the source rental’s rent, yet the lender on the new purchase must accept borrowed money and may cap the borrowed share. Closing costs and reserves are tested separately, and a fully borrowed down payment leaves you with no cash of your own in the deal.
Does the line’s payment lower the DSCR on the new short-term rental?
No, not in the new property’s coverage ratio. A DSCR purchase compares that property’s income with its own payment. The line’s payment still comes out of your cash flow, so a thin property can look fine on paper and still strain you each month.
Can I draw on my own home instead?
Not under this program. The line is offered only on non-owner-occupied rentals, never on an owner-occupied home. A line on your residence is a separate bank product that relies on personal income, and the purchase lender’s borrowed-funds rule still applies.
Can the source rental sit in an LLC?
Yes, vesting in your LLC is allowed on an investment property, subject to program terms. Title holders who are not borrowers sign an acknowledgment, and the borrowers on the line need not match the borrowers on the first mortgage.
Which states offer this program?
It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through select programs and subject to underwriting.
